In Azure ML, what is the artifact generated after training a model?

The artifact generated after training a model in Azure ML that is crucial for future tasks is the model file or serialized object for inference. This serialized object encapsulates the learned parameters and configuration of the model, enabling it to be utilized for making predictions on new data. When a model is trained, it essentially transforms its learned patterns into this file format, which allows the model to be easily deployed or shared. This artifact is vital for operationalizing the model in production environments, as it can be loaded and used without needing to retrain the model each time.

Other artifacts like a summary report of model performance provide insights into how well the model may perform but do not contain the actual model needed for making predictions. Similarly, the dataset used for training, while essential for model development, does not serve as the output of the training process. A visualization of the model architecture aids in understanding the model's structure but does not represent the actual trained model itself. Thus, the model file or serialized object is the primary artifact that directly results from the training process and is essential for practical deployment and inference tasks.
